摘要：MANET consists of a group of wireless nodes, which help each other in forwarding packets to enable communications. This type of network requires no fixed network infrastructure [11]. Since the node may change their position unpredictably, the data transmission can be temporarily disturbed if any link on the path fails. Ad hoc routing protocols have been designed to reroute traffic when opposed with network congestion, faulty nodes, and dynamically changing topologies. The common design objective of ad hoc routing protocols is to faithfully route packets from a source node to a destination node. Detecting nasty nodes in an open ad hoc network in which partaking nodes have no previous security associations presents a number of challenges not faced by wired networks. Unless an alternate path is immediately available, the packets are likely to be lost or delayed. An ad hoc network does not have different types of network elements like switches, hubs etc. where the Intrusion Detection System (IDS) can collect and assess assessment data for the whole network. A number of neighbor-monitoring, trust-building, and cluster-based voting schemes have been proposed in the research to enable the detection and reporting of nasty activity in ad hoc networks. The resources consumed by ad hoc network member nodes to monitor, detect, report, and diagnose nasty activity, however, may be greater than simply rerouting packets through a different available path. To overcome this problem[2] suggest some technique such as using the two-hop routing information and data buffering [1] [2]. The route caching [9] has been suggested many a times but the data packet buffering has been given some attention. In this paper we propose the new design for enhancing the performance of MANET by buffering the data and providing an alternate path for the packet to reach their destination.
